fix(gc): fix cleaning deduped blobs because they have the modTime of the original blobs, fixed by updating the modTime when hard linking the blobs. fix(gc): failing to parse rootDir at zot startup when using s3 storage because there are no files under rootDir and we can not create empty dirs on s3, fixed by creating an empty file under rootDir.
